The IRONZON 291Y is a matte black smart door knob that replaces a standard knob and unlocks four ways: fingerprint, keypad code, app, or a physical backup key. It stores up to 50 fingerprints and 100 passcodes, adds one-tap privacy mode and auto-lock, and installs on standard US doors in about 10 minutes. App control needs a separate gateway, so remote access is an add-on rather than included. It suits renters and homeowners wanting keyless entry on a bedroom, interior or front door without a full deadbolt system.

The IRONZON 291Y is a 4-in-1 smart door knob in matte black. It unlocks four ways: by fingerprint, keypad code, app, or one of two backup keys. It can be used on bedroom, interior, front, apartment, office and garage doors.
The lock is made from high-strength metal, zinc alloy and stainless steel. It has a one-tap privacy mode setup and an auto-lock function. The keypad is designed to be anti-peep, and data is stored locally.
App control requires a gateway, which is sold separately. The lock is made for standard U.S. doors, and installation takes about 10 minutes.
